Clay-Sawdust Ceramic Pot Filter (Potters for Peace Design)¶

Ceramic Filtration • Est. CapEx: $8 USD • Lifespan: 10 Years (Standardized)

Technical Overview¶

A porous ceramic water filter made from a mixture of clay and sawdust (or other combustible material) fired to create microscopic pores that trap pathogens and sediment. It is a low-cost, field-tested solution for household water treatment in developing regions, with open-source manufacturing guides available.

Key Specifications & Engineering Parameters¶

Parameter	Specification
Category	Ceramic Filtration
Capital Cost (CapEx)	$8 USD
Power / Energy	100% Gravity / Zero Power
Target Scale	Household (5–10 people)
Standard Lifespan	10 Years (Standardized)
Technology Maturity	Field Tested
Primary Mechanism	Water flows through the ceramic pot by gravity. Physical filtration occurs when pores (0.6-3.0 µm) trap bacteria and protozoa. Colloidal silver coating provides additional antimicrobial action by disrupting pathogen cell membranes. Adsorption on clay surfaces also helps remove some contaminants.
